PLEASE HELP ME !!!!!

Answer 1

I’m sorry but I really don’t understand that...

Answer 2

Answer:

512 inches³

Step-by-step explanation:

First, you need to know the equation for the surface area of a square prism:

SA = 6(L²)

(L²) is the equation to find the area of a square. Since a square prism has 6 square faces, we would multiple the area of one of the faces by 6 to get our surface area. (I use L² rather than L · W since the length and width are the same since this is a square.)

6(L²) = 384

Divide each side by 6.

6(L²) = 384

L² = (384 ÷ 6)

L² = 64

Find the square root of each side.

L² = 64

L² = √64

L = 8

Now that we know the exact value of each side of our square prism, we can use L³ (L · W · H) to get our volume.

8³ = 512 inches³
